Non-Turbo

Fig. 25 Throttle Position Sensor:

When in the idle position, contact is made between terminals 1 and 2 of the throttle position sensor, Fig. 25. At this time, terminal 30 in the deceleration relay and terminal TRK in the time relay are grounded.
Once the throttle butterfly opens beyond 72°, contact is made between terminals 2 and 3, a ground signal is received from terminal TK in the AC relay, and the electromagnetic clutch on the AC compressor is disengaged.
